银川市住宅小区用电负荷及线损率连续监测分析

摘要

针对银川市住宅小区配电变压器负荷率普遍较低的现状，选取银川三区典型居民住宅小区为监测对象，对住宅小区用电负荷及线损率进行连续监测，通过对监测数据的分析，提出了合理配置住宅小区配电变压器报装容量，优化变压器运行方式，减少变压器损耗及线路损耗的建议。监测结果表明：银川居民住宅小区普遍存在配电变压器设计容量偏大、运行负载率偏低现象。%Aiming at the status quo of lower power load of distribution transformer for residential quarters in Yinchuan, selecting typical residential quarters as the monitoring object in three district of Yinchuan City, makes continuous monitoring for power load and line loss of residential quarters. through analyzing the monitoring data, puts forward the suggestion that rationally allocation distribu- tion transformer capacity of residential quarters, optimizes operation mode of distribution transformer, reduce transformation loss and line loss.The result shows that residential quarters of Yinchuan City commonly exist the phenomena of distribution transformer' s design capacity larger than real capacity and power operation load factor lower.
